files
input: a text file
output: each line of the input is typed backwards
description
Lines of the input are read in, stored and put out in the reverse order.
This allows one to reverse a line, trim off the *last* few characters with
the unix cut program and then flip it around again to obtain a specific
number of characters off the end.
